The article discusses NIST’s research in quantum information science, focusing on quantum communications and their potential applications. Quantum communications involve exchanging information encoded in quantum states of matter or light between quantum systems. NIST has demonstrated high-speed quantum key distribution (QKD) systems for secure communications, extending them into a 3-node quantum network. However, limitations like communication distance (around 100 km) exist. Quantum repeaters are a promising solution to extend communication distances, but significant challenges remain. NIST’s research aims to identify these challenges, find solutions, and evaluate their capabilities for future quantum communication applications, promoting US innovation and industrial competitiveness.
